```
public class _StlExporter
extends _VrmlExporter
```
STereoLithography file format exporter for 3D printing. Based on _VrmlExporter by Bob Hanson; diverts the output() method to do nothing and delivers only triangle sets. Note that no attempt is made here to ensure that surfaces are closed. Also, an inefficient mechanism that involves creating a full in-memory representation of the data is used. If this turns out to be problematic, it might be possible to use random access, but the applet does not have that capability, and certainly JavaScript does not.
